True or false?

TRUE:

A. Mesenteric cysts are most often due to congenital lymphatic spaces that gradually fill with lymph.

B. Mesenteric cysts usually present as abdominal masses accompanied by pain, nausea, or vomiting.

D. Omental cysts are frequently asymptomatic unless they undergo torsion.

FALSE:

C. Mesenteric cysts are best treated by marsupialization

DISCUSSION: Mesenteric cysts are most often due to congenital lymphatic spaces that gradually enlarge as they fill with lymph. They generally present as abdominal masses accompanied by pain, nausea, and vomiting. They usually can be diagnosed by physical examination and have characteristic lateral mobility. They are best treated by surgical excision, and intestinal resection may be necessary for complete removal. Omental cysts are frequently asymptomatic but may present with vague discomfort or as a mobile abdominal mass that can cause torsion of the omentum. Torsion generally presents with signs and symptoms compatible with acute cholecystitis, appendicitis, or a twisted ovarian cyst. Treatment entails local resection.
